Tempest 2 vs DynaVap M7: Which Butane Vaporizer Fits You Better?
TEMPEST 2 and DynaVap M7 are butane vaporizers without a battery: you heat the cap with a torch lighter or an induction heater and draw immediately afterward. The TEMPEST 2 by MAD Heaters (from 202.21 € incl. shipping) is a ball vaporizer made from Grade 5 titanium with zirconia balls in the cap, three fill sizes, and two separately adjustable airflow paths. The M7 by DynaVap (from 71.98 € Code VAPOCHECKER10 · incl. shipping) is a slim stainless steel stem with a click cap and a 0.1 g chamber that can be halved.

How do the TEMPEST 2 and M7 heat?
Inside the TEMPEST 2 cap sits a bed of 3 mm zirconia balls. The inhaled air passes through the heated balls and then through the herb; MAD Heaters describes this principle as predominantly convection. According to the manual, where you position the flame shifts the balance between convection and conduction. The balls are replaceable: in addition to zirconia, MAD Heaters also offers ruby, quartz, and SiC balls that retain heat for different lengths of time.
In the M7, the stainless steel cap sits directly above the chamber. It transfers heat through the wall to the herb and simultaneously heats the air that flows through the chamber when you draw. DynaVap therefore classifies the M7 as a hybrid. According to the manufacturer, the redesigned cap increases the convection share compared to older M models.
How do you know when the right temperature is reached?
Easier: DynaVap M7. The cap clicks once the chamber reaches extraction temperature. Then you draw. When the cap cools down, it clicks again, and you can reheat. There is nothing more to remember.
The TEMPEST 2 has two click discs in the head and additionally a visual display on the cap. According to the manual, the first click usually comes at the lower end of the ideal range; using the visual display, you can continue heating with more precision. The two discs can click simultaneously and change slightly over the first 30 to 50 uses.
Torch lighter or induction heater?
Both work with either. MAD Heaters recommends a two- or three-flame torch lighter for the TEMPEST 2, or a medium single flame, and lists the iSpire Wand and the YLL 3.0 as induction heaters. The Wand’s opening must be at least 14.0 mm wide. When using the Wand, you do not set a temperature but a heating duration: according to the manual, the displayed value — for example, 290 °C — acts as a timer. With the YLL 3.0, power, timer, and insertion depth follow the tables in the manual.
DynaVap also recommends a butane lighter or an induction heater for the M7 and includes a single-flame DynaTorch, without gas fill. DynaVap offers its own induction heaters under the DynaTec name.
How much fits in the chamber and how do you adjust the airflow?
In the TEMPEST 2, the screen position determines the fill size: approximately 0.1, 0.15, or 0.2 g. You adjust the airflow at two points. At the cap, you loosen the top screw, rotate the induction sleeve, and retighten the screw. At the stem, you loosen the mouthpiece and rotate the heat shield until the airflow inlet is as open or closed as you prefer.
The M7 holds approximately 0.1 g. With the Adjust-a-Bowl insert, you halve the chamber for smaller amounts. You adjust the airflow at the inlet using the Pivot carb. That means fewer adjustments than on the TEMPEST 2, but the device is set up more quickly.
Size, weight, and water pipe
The TEMPEST 2 measures 122 × 18.5 mm and weighs 46 g with the aluminum heat shield, 43 g with the wood heat shield. The M7 weighs 17 g and therefore less than half as much; as a slim stem it fits more easily in a pocket.
To use on a water pipe, the TEMPEST 2 fits directly into joints of 10, 14, and 18 mm according to MAD Heaters. According to the current DynaVap product page, the M7 fits directly into 10 mm joints; for 14 or 18 mm you need an adapter.
What warranties do the manufacturers offer?
MAD Heaters provides a one-year warranty on the TEMPEST 2 against material and manufacturing defects under normal use. Excluded are misuse, accidents, modifications, and normal wear and tear.
DynaVap covers functional defects on devices it manufactures itself, such as the M7, without any time limit. Excluded are screens (CCDs), O-rings, replacement media, and accessories, as well as damage caused by improper use or maintenance. Additionally, there is a 90-day money-back guarantee.

Who should buy which device?
- TEMPEST 2, if you want to choose the fill size, adjust the airflow at two points, and swap the ball material; if you use both the click and the visual display; and if your water pipe has 14 or 18 mm joints. With the YLL 3.0 or Wand, you can heat it without an open flame.
- DynaVap M7, if you are looking for a small, lightweight device with a simple click-based workflow, often take small amounts, and want to spend less. DynaVap sells caps, mouthpieces, and stems individually, so you can customize the device later.
Our Verdict
The premium for the TEMPEST 2 pays for adjustability: three fill sizes, two airflow paths, replaceable balls, three joint sizes, and a visual display in addition to the click. Anyone who will actually use these settings gets a tool for fine-tuning. Anyone who wants to heat, wait for the click, and draw will get there faster with the M7 and pay considerably less.
Frequently Asked Questions
Is the TEMPEST 2 a purely convection vaporizer?
MAD Heaters describes it as predominantly convection: the air passes through a bed of heated zirconia balls and then through the herb. According to the manual, where you position the flame changes the conduction share.
Can both be used with an induction heater?
Yes. MAD Heaters lists the iSpire Wand and the YLL 3.0 for the TEMPEST 2; DynaVap recommends a butane lighter or an induction heater for the M7. Power, heating duration, and insertion depth are covered in the manufacturers’ manuals.
Which is better for small amounts?
Both. The M7 holds approximately 0.1 g, and with the Adjust-a-Bowl insert, half that amount. The TEMPEST 2’s smallest screen position also holds approximately 0.1 g.
Do both fit on a water pipe?
Yes. According to MAD Heaters, the TEMPEST 2 fits directly into joints of 10, 14, and 18 mm. The M7 fits directly into 10 mm joints; for larger joints you need an adapter.
What does the 290 °C setting on the Wand mean?
According to the TEMPEST 2 manual, the displayed value on the iSpire Wand acts as a timer for the heating duration. It does not indicate the temperature in the herb.
